These are the best pajamas I've found and I've bought several brands. So damn comfortable I will ONLY buy iZOD PAJAMAS. I bought a pair of these pajamas from the store hoping they were exactly the same because they were so comfortable compared to other brands I had bought. Many pajama brands have a tie at the top where they are sewn on, or because they have a thick elastic band at the waist. Who wants to sleep when a bunch of fabric and rubber bands are folded up and digging into your thigh bones if you sleep on your side? Buy iZod and you will sleep better!
